Regions: Jasper.

Like lipstick on a Pig, the incoming storm snow will bury early season hazards at lower elevations and build onto the wind slab tree line and above.

Weather Forecast

10-25cm forecasted for the Icefields Parkway Thursday night and into Friday, which will be accompanied by moderate south winds. The weekend will bring scattered flurries, light winds with mainly cloudy skies.

Snowpack Summary

On lee slopes, wind slab sits on top of a 5-10cm thick crust between roughly 2100m and 2600m. These slabs may be touchy in cross-loaded areas within the elevation band where the crust exists. Facets are present on top of the crust and will be the layer to watch with the incoming storm snow.

Avalanche Summary

No new avalanches observed

Confidence

Intensity of incoming weather systems is uncertain on Friday

Avalanche Problems

Wind Slabs

Be cautious of wind slab in immediate lee and cross-loaded terrain in the alpine.
Be cautious of buried obstacles in shallow snowpack areas.Use caution in lee areas in the alpine and treeline. Recent storm snow has formed wind slabs.

Aspects: North, North East, East, South East, South.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 3
